Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automobile door, and more specifically, a stopper that engages with a locking pawl on a windshield is formed on the inside of an outer panel of a plastic door. The invention relates to automobile doors.

[Conventional technology]

Automobile doors are equipped with window glass that moves up and down, but on doors with a window frame, the window glass moves up and down along the window frame, and when the window is fully closed, the frame groove prevents the window glass from coming off. It is designed to prevent outside noise and rainwater from entering.

On the other hand, in a hard-top type car, the door does not have a window frame, and when the window glass is closed, the end surface of the window glass only comes into contact with the sealing member attached to the frame of the car body. The surroundings are not designed to hold. As a result, the windshield often vibrates when the car is driven at high speed and the windshield is sucked outward.

For example, Japanese Patent Laid-Open Publication No. 1983-1970 is a device that can prevent such vibration of the windshield.
There is an anti-shake device for automobile window glass described in Japanese Patent No. 159482. Furthermore, there is a vibration prevention device for automobile door glass described in Japanese Utility Model Application Publication No. 52-33819.

In these systems, an elastic body or flexible member is inserted between the outer panel and the inner panel that form the door body or in the window regulator, and the lower part of the raised window glass is pressed by the elastic body or flexible member, causing the backlash of the window glass. It is designed to prevent sticking.

The pressing member necessary for this purpose is newly provided to prevent vibration of the window glass, and requires new manufacturing effort such as manufacturing new parts and mounting work. Moreover, in order to prevent the window glass from rattling, the above-mentioned pressing member always slides on the window glass itself or the bracket holding the window glass.
Frictional force acts each time the window glass is raised and lowered, and a relatively large opening/closing force is required.

[The problem that the idea aims to solve]

By the way, recently, plastic panels are being used instead of steel plates for the outer panels of doors. Therefore, if you take advantage of the advantages of plastic molding when manufacturing plastic doors, you can incorporate anti-vibration measures with less cost and effort, which is extremely convenient from the standpoint of manufacturing costs.

If it is thereby possible to prevent rattling even in the elements additionally formed on the outer panel, it is possible to effectively suppress vibrations of the windshield that occur in hard-top type cars, etc., in particular. Therefore, when a plastic outer panel is employed, it is desirable to develop a door that is provided with a vibration prevention means that is convenient for molding.

By the way, in Japanese Utility Model Publication No. 57-33174, a regulating stopper is provided at the upper part of the inner panel of the door, and a locking stopper is provided at the lower end of the window glass, so that both stoppers are engaged when the window glass is raised to the maximum. A stopper structure for a window glass is described.

However, the stopper is manufactured separately from the inner panel, and is attached with bolts and nuts. Therefore, the stopper must be manufactured in advance, and the number of installation steps required to attach the stopper to the inner panel increases. Another disadvantage is that the number of parts such as stoppers, bolts, and nuts increases, which complicates the man-hours required to manufacture the door assembly.

In other words, measures to prevent windshield vibration require parts and man-hours that are only necessary for this purpose, and it is necessary to increase the diversity of functions, such as improving the rigidity of the inner panel. There is a drawback that it cannot be used to its full potential in one element.

The present invention was developed in view of the above-mentioned problems, and its purpose is to add desired functions to parts of the plastic outer panel that have other functions, thereby achieving multifunctionality while maintaining a simple structure. To suppress the increase in the number of parts, and to provide desired functional elements in one piece without making any major changes to the plastic outer panel, thereby reducing the effort required to install single functional parts. To provide an automobile door which can prevent the generation of vibrations in the left and right directions due to the sucking phenomenon of the windshield and the rattling of the windshield in the front and back directions.

[Means to solve the problem]

The present invention is applied to an automobile door structure whose outer panel is made of plastic.

Its feature is that, with reference to FIGS. 1 and 2, a plurality of reinforcing ribs 3, 3 extending vertically are formed integrally with plastic molding in the front-rear direction of the vehicle body inside the outer panel 1. Ru. On the other hand, on the outer surface of the lower end of the window glass 2, at respective positions corresponding to the reinforcing ribs 3, 3,
Locking claws 7, 7 protruding in the front-rear direction are attached. At the upper ends of the reinforcing ribs 3, 3, stoppers 4, 4, which engage with the locking claws 7, 7 to prevent movement of the window glass 2 when the window glass 2 is fully closed, extend in the front-rear direction. It is formed by bending it like this.

[Effect of idea]

According to the present invention, the locking pawl and the stopper engage only when the window glass is fully closed, thereby preventing rattling of the window glass, vibration due to wind pressure, and rattling in the front-rear direction. Its anti-vibration structure takes advantage of the fact that the outer panel is made of plastic.
Since it can be formed during the molding stage, it is possible to reduce the manufacturing and mounting work of parts. Moreover, since it utilizes the reinforcing ribs required when forming the outer panel,
The rigidity of the outer panel can be increased, the degree of modification thereof is small, and even though the panel structure is simple, it can be made multifunctional, and an increase in the number of parts can be suppressed.

〔Example〕

The present invention will be described in detail below based on examples thereof.

FIG. 2 is a perspective view of the outer panel 1 and the window glass 2 of a door to which the present invention is applied in a separated state. The windows can be opened and closed.

This outer panel 1 is an integrally molded plastic product, and has reinforcing ribs 3 formed thereon to increase rigidity along with edge portions forming the periphery of the door. As a general rule, the entire central surface of the outer panel 1 is slightly bulged, and in order to reinforce the panel with such a shape, for example, two reinforcing ribs 3, 3 protrude toward the inside of the vehicle. It is molded to extend in the vertical direction.

In the case of this example, the reinforcing ribs 3, 3 have a substantially uniform cross section from the bottom to the vicinity of the top, and are formed so as to protrude perpendicularly to the outer panel 1, that is, toward the passenger compartment side. At the upper end thereof, stoppers 4, 4 are formed by bending and molding the tips of the reinforcing ribs 3, 3 so as to extend in the longitudinal direction of the vehicle.

These stoppers 4, 4, in the two reinforcing ribs 3, 3, are opposed to each other as shown in the figure, or are oriented in opposite directions (not shown). Between the stoppers 4, 4 and the outer panel 1, as shown in FIG. There is.
Therefore, the reinforcing ribs 3, 3 on which the force acts
are provided with fine ribs 5 as necessary, locking claws 7,
7 is provided on the side through which it does not pass.

Since the outer panel 1 is a plastic molded product, the stoppers 4, 4 can be integrally molded relatively easily, and the stoppers 4, 4 can be integrally molded.
4 on the outer panel 1, no new parts are required, and no special installation work is required. Moreover, since it is provided so as to be continuous with the reinforcing ribs 3, 3 required for molding, there is an advantage that there is no need to make any major modifications to the outer panel 1.

On the other hand, metal fittings 6, 6 are attached to the lower end of the window glass 2 so as to sandwich the glass.
Locking claws 7, 7 are formed at one end thereof. The locking claws 7, 7 extend from the outer surface of the window glass 2 toward the outer panel 1, and are installed at positions corresponding to the reinforcing ribs 3, 3 mentioned above. Therefore, the locking claws 7, 7 move up and down along the reinforcing ribs 3, 3, and are raised and lowered together with the window glass 2 at a position close to the inner surface of the outer panel 1.

As a result, when the window glass 2 is raised significantly, the locking claws 7, 7 are sandwiched between the stoppers 4, 4 and the inner surface of the outer panel 1, and the window glass 2 is held without wobbling at the bottom. It is becoming more and more like this.

According to such a configuration example, even in a hard-top type car, the locking claws 7, 7 at the lower part of the window glass 2 are restrained by the stoppers 4, 4 when the window glass 2 is fully closed.

When the car is running at high speed, the pressure on the outer surface of the fully closed window glass 2 decreases due to airflow, and the pressure difference between the windshield 2 and the passenger compartment causes the windshield 2 to be sucked outward. However, even if this force acts on the window glass 2, the lower part of the glass is held without wobbling, so the generation of vibrations is suppressed.

As can be seen from the above description of the embodiment, the locking pawl protruding from the lower end of the window glass is engaged with the stopper at the upper end of the reinforcing rib formed on the plastic outer panel. The locking pawl and the stopper engage only when the window glass is fully closed, thereby preventing rattling of the window glass and vibration due to wind pressure. The anti-vibration structure can be formed at the molding stage by taking advantage of the fact that the outer panel is made of plastic, so it is possible to avoid manufacturing separate parts and installing them. Moreover, since the reinforcing ribs required for molding the outer panel are used, the degree of alteration of the outer panel can be reduced.

That is, in order to prevent rattling, a cushioning material such as rubber is not necessarily required, and the structure of the stopper becomes simple. Further, the reinforcing ribs can exhibit the double effect of reinforcing effect and stopper effect, and no special complexity is required in manufacturing the plastic outer panel. In addition, the locking pawl and the stopper only engage when the window glass is fully closed and the glass is raised; This has the advantage that a large operating force is not required to raise and lower the window glass.
